I noticed this forum looks a bit dead from the last time I visited but I figured it was helpful the last time round so I'd give it a shot.

Basically my zune 120gb stopped functioning a few weeks ago (i.e. won't turn on, won't charge etc). I've managed to disassemble and pry open the casing as I'm contemplating buying spare parts for it as opposed to another one.

The problem is I'm not sure what exactly the problem is with my zune? Is it the hard drive that needs replacing or the battery? Is there anyway for me to find out or test the components, in particular the hard drive?
